PHARMACEUTICAL COMPOUND.
No brewing.
To all whom it may concern:
Be it known that I, HANS HAHL, a citizen of Germany, residing at Elberfeld, in the State of Prussia, Germany, have invented new and useful Improvements in Pharma-- ceutical Compounds, is a "specification.
The present invention relates to the manufacture and production of new products being chemically'basic para alkylethers of polyvalent phenols of the benzene series. They have proved to be useful in the treatment of diseases of the heart and are oils forming whitish crystalline salts with acids, soluble in water.
One process for producing the new products consists in heating mono-alkylethers of hydrolquinone with basic alkylhalides.
In order to illustrate the new process more fully, the following example is given, the parts bein by Weight:
3.7 parts 0 sodium are dissolved in parts ofalcohol and 20 parts of hydroquinone monomethyl ether and 25 parts of chloroetliyldiethylamine are added. The reaction begins in the cold and is completed by gently heating. The mixture is poured into water and the oil which precipitates is separated, dried and distilled in vacuo.
Under a pressure of, 15 mm. the diethyl amino ethyl hydroquinone monomethylether distils 'over as a limpid oil having the formula:
of which the following OCH;
eases, substantial] Application filed December 18, 1924. SeriaI No. 758,819.
It forms crystalline salts with acids. .The hydrochloride crystallizes from acetic acid ester in the shape of needles melting at 12l122 C.
1. As new products, dialkylethers of hydroquinone containing a basic alkyl radicle, being oils forming crystalline whitish salts with acids and being useful in the treatment of diseases of the heart.
2. The herein described new diethylaminoethyl-hydroquinone-monomethyl ether having the formula:
Kl: .CH: N (Ci a):
being an oil forming a White crystalline hydrochloride melting at 121122 (1; and being useful in the treatment of heart disas described. In testimony w ereof I have hereunto set my hand.
HANS HAHL.
